Canadian Boating Practice Exam

Vessels under oars at night are required to have a white light that is visible in all directions. This is to ensure visibility for other boats in the area. If the vessel only had red and green sidelights or a sternlight, it could potentially be difficult for other boats to see and avoid the vessel, as these lights are not visible from all directions. And while it may seem logical that no lights are required for vessels under oars, this is not the case as they are still considered a moving vessel and must follow navigational rules for safety. Therefore, the minimum light requirement for vessels under oars at night is a white light that can be seen in all directions.
